Scientific Data Images for Human CD45RA Antibody

Detection of CD45RA in PBMC lymphocytes by Flow Cytometry.

PBMC lymphocytes were stained with Mouse Anti-Human CD45RO PE‑conjugated Monoclonal Antibody (Catalog # FAB10642P) and either (A) Mouse Anti-Human CD45RA Monoclonal Antibody (Catalog # MAB11446) or (B) Mouse IgG1 Isotype Control (Catalog # MAB002) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B).

Detection of CD45RA in Human Tonsil.

CD45RA was detected in immersion fixed paraffin-embedded sections of Human Tonsil using Mouse Anti-Human CD45RA Monoclonal Antibody (Catalog # MAB11446) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cell surface in lymphocytes.

Background: CD45RA

CD45RA is a single chain type I glycoprotein that is encoded by the human PTPRC gene.  In humans, CD45RA is one of six isoforms of the CD45 complex. These different isoforms are the result of alternative splicing and some of the other isoforms include CD45RO, CD45RB, and CD45RC. CD45RO, CD45RB, CD45RC, and CD45RA are primarily expressed on T cells. CD45RA contains exons 3, 4, and 7 but lacks both exons 5 and 6; CD45RC contains exons 3, 6, and 7. CD45RO contains exons 3 and 7 whereas CD45RB contains exons 3, 5, and 7. Both CD45RA and CD45RB are highly expressed on naïve T cells whereas CD45RO is expressed on activated and memory T cells in addition to some B cell subsets and activated monocytes. Both CD45RA and CD45RO are routinely used to characterize different subsets of Memory T cells.
